Description

Technical Field

[0001] The present invention belongs to the field of steel wire rope detection, and more particularly, relates to a swinging steel wire rope detection device. Background Art

[0002] Hoists are commonly used in offshore oil platforms, drilling equipment, subsea engineering, and lifting and transport applications to lift and lower heavy objects. Wire ropes are a key component of these hoists. Regular wire rope inspections can identify problems such as damage, broken wires, wear, corrosion, and deformation. This helps prevent potential accidents and ensures safe equipment operation.

[0003] At present, when inspecting wire ropes, the detection device is usually installed and fixed first, and then the wire rope is passed through the detection device. For example, the Chinese patent application number 202110924291.3 discloses a wire rope damage detection device based on magnetic flux changes and its method, including a detection platform, and the left and right sides of the detection platform are provided with walking components for positioning and walking on the wire rope, and a magnetic flux detection component is provided on the detection platform between the two walking components, and a PLC controller is provided on the outside of the detection platform; the walking component includes a bracket, one side of the bracket is fixedly connected to the detection platform, and one side of the bracket is respectively provided with an upper hanging wheel and a lower positioning wheel, and the upper hanging wheel is rotatably arranged at the upper end of the bracket and driven to rotate by a motor. The detection device is conveniently assembled and connected with the wire rope through the walking component, thereby realizing the traveling detection of the wire rope, and the split design of the first magnetic flux sensor and the second magnetic flux sensor in the magnetic flux detection component realizes non-destructive detection of the wire rope.

[0004] The following problems exist in the existing related technologies: the angle of the detection platform is fixed, and when the winch reels the wire rope, it usually causes the wire rope to swing left and right significantly to evenly wind it on the reel. However, due to the heavy weight of the wire rope, its inertia during swinging is large, and the wire rope generates high-speed vibration due to the high-frequency alternating load. Under high-speed vibration, the wire rope is not only prone to damage to the detection device, but the wire rope may also slip out of the magnetized body and the sensor detection hole, resulting in missed detection, affecting the accuracy of the wire rope detection results. Summary of the Invention

[0005] In order to facilitate the detection of a steel wire rope that swings greatly, the present invention provides a swinging steel wire rope detection device.

[0006] The present invention provides a swinging wire rope detection device that adopts the following technical solutions:

[0007] A swinging wire rope detection device includes a fixed base, a detection mechanism and a swinging mechanism; wherein the swinging mechanism includes a rocker arm, a first movable connection component and a second movable connection component; one end of the rocker arm is connected to the fixed base through the first movable connection component, and the detection mechanism is installed on the other end of the rocker arm through the second movable connection component; the rocker arm is able to swing left and right and up and down through the first movable connection component, and the detection mechanism is able to swing left and right and up and down through the second movable connection component; the detection mechanism includes a positioning component and two detection probes, a detection area is formed between the two detection probes, and the positioning component is used to fix the positions of the two detection probes.

[0008] By adopting the above technical solution, when testing the wire rope, two detection probes are set on the outside of the wire rope, and the wire rope is tested by the detection probes. The detection mechanism is installed on the rocker arm, and the detection mechanism can swing up and down and left and right with the rocker arm. At the same time, the detection mechanism can adjust the angle on the rocker arm. When the detection mechanism detects the wire rope and the wire rope swings, the detection mechanism first adjusts the angle as the angle of the wire rope changes, and then changes the position of the detection mechanism as the wire rope moves, so that the detection mechanism and the wire rope are relatively stable, so that it is suitable for testing the swinging wire rope.

[0009] As a further preferred embodiment, the first movable connection assembly includes a first rotating seat and a first connecting frame, the first rotating seat is rotatably connected to the fixed base and the rotating axis is vertically set, the first connecting frame is fixedly connected to the first rotating seat, the rocker arm is rotatably connected to the first connecting frame and the rotating axis is horizontally set.

[0010] By adopting the above technical solution, the rocker arm can achieve large-scale height adjustment and angle change through the first rotating seat and the first connecting frame, so as to adjust the position of the detection mechanism and maintain relative stability with the moving wire rope, thereby realizing the detection of the wire rope.

[0011] As a further preference, the first movable connection assembly further includes a connecting rod and a plurality of tension springs, the connecting rod is fixedly connected to the first rotating seat, and the plurality of tension springs are arranged parallel to each other and connected between the connecting rod and the rocker arm.

[0012] By adopting the above technical solution, a tension spring is used to provide tension to balance the gravity of the rocker arm and its upper part to generate a torque to maintain the stability of the rocker arm during movement.

[0013] As a further preferred embodiment, an extension rod is fixedly connected to the connecting rod and the rocker arm, the extension rod is parallel to the rotation axis of the rocker arm, a plurality of positioning grooves are provided on the extension rod, and both ends of the tension spring are fixedly connected to a connecting ring which is sleeved on the extension rod and embedded in the positioning groove.

[0014] By adopting the above technical solution, the tension spring is connected between the two extension rods, so that the multiple tension springs are arranged more evenly, and the connecting ring is embedded in the positioning groove, thereby improving the stability of the tension spring.

[0015] As a further preferred embodiment, the second movable connection assembly includes a second rotating seat and a second connecting frame, the second connecting frame is rotatably connected to the rocker arm and the rotation axis is parallel to the rotation axis between the rocker arm and the fixed base, the second rotating seat is fixedly connected to the second connecting frame, and the two detection probes are rotatably connected to the second rotating seat through a positioning assembly and the rotation axis is perpendicular to the rotation axis of the second connecting frame.

[0016] By adopting the above technical solution, the detection probe can be swung up and down by rotating the second connecting frame, and the detection probe can be rotated in the horizontal direction by rotating the second rotating seat, so that the wire rope is kept between the detection probes when it rotates left and right or moves up and down during the winding operation, thereby improving the accuracy of the detection results.

[0017] As a further preferred embodiment, the positioning assembly includes two brackets, the two brackets are connected in an openable and closable manner, the two detection probes are connected in an openable and closable manner, and the opening and closing direction is the same as the opening and closing direction of the two brackets, one of the detection probes is fixedly connected to the bracket on the same side, one side of the two detection probes is connected by a hinge, and the other side of the two detection probes is detachably connected.

[0018] By adopting the above technical solution, when the two brackets are opened, the two detection probes are opened by the hinges, so that the two detection probes can be put on the outside of the wire rope. After the two detection probes are closed, the two brackets are put on the outside of the wire rope, and then the two brackets are fixed by bolts to complete the installation of the detection probes. The installation is stable and efficient.

[0019] As a further preferred embodiment, the positioning assembly also includes a roller frame, a roller and an adjusting member, the roller is rotatably connected to the roller frame, the roller frame is rotatably connected to the bracket, the rotation axes of the roller frame and the roller are parallel to each other, and the adjusting member is used to drive the roller frame to rotate so that the roller abuts against the outer wall of the wire rope to be tested.

[0020] By adopting the above technical solution, the roller is connected to the bracket through the roller frame, so that after the wire rope passes through the roller to fix the position, the wire rope can move, reducing the damage to the wire rope caused by friction, and the distance between the two rollers is adjusted according to the diameter of the wire rope, which is suitable for detecting wire ropes of various rope diameters. At the same time, the wire rope is kept in the middle of the detection probe to obtain a stable and accurate detection signal. At the same time, the rotational stiffness of the roller frame is adjusted by the adjustment part to change the force between the roller and the wire rope, thereby preventing impurities attached to the wire rope from causing the bracket to shake and affecting the stability of the probe detection.

[0021] As a further preferred embodiment, the adjusting member includes an articulated screw, a spring, a first support seat, a second support seat and a nut, one end of the articulated screw is rotatably connected to the end of the roller frame away from the roller, the first support seat is fixedly connected to the bracket, the articulated screw passes through the first support seat, the spring, the second support seat and the nut in sequence, and the articulated screw is threadedly connected to the nut.

[0022] By adopting the above technical solution, under relatively clean working conditions, when it is necessary to increase the rotational stiffness of the roller frame, the detection probe is made to follow the wire rope closely to ensure that the relative displacement on the cross section remains unchanged, and a better quality acquisition signal is obtained. The nut is rotated to adjust its position on the articulated screw to drive the second support seat compression spring. When the spring drives the second support seat and the articulated screw to move in opposite directions, the roller frame rotates, thereby increasing the force between the roller and the wire rope, and further improving the stability between the bracket and the wire rope. Under relatively harsh working conditions, there are a lot of oil, dust, stones, etc. on the wire rope, and the roller frame requires a relatively small rotational stiffness. If a larger rotational stiffness is used, impurities on the wire rope will cause the probe to move violently, resulting in unstable signals. In addition, the collision of impurities with the roller will cause the wire rope to be scratched, so the nut is rotated in the opposite direction for adjustment.

[0023] As a further preference, one end of the fixed base is provided with a connection portion for connecting to a winch, and a support assembly is further provided between the fixed base and the winch.

[0024] By adopting the above technical solution, the fixed base is connected to the winch through the connecting part to form a whole, so that the position of the fixed base is fixed, thereby improving the stability of the swing mechanism and the detection mechanism during the wire rope detection process.

[0025] As a further preference, the support assembly includes a connecting plate and a support rod, one end of the support rod is fixedly connected to the connecting plate, and the other end of the support rod is fixedly connected to the fixed base.

[0026] By adopting the above technical solution, the connecting plate is fixedly connected to the winch, the support rod is connected to the fixed base, and a triangular structure is formed between the support rod, the fixed base and the winch, thereby further improving the stability between the fixed base and the winch.

[0027] In summary, the present invention has at least the following beneficial technical effects:

[0028] 1. When testing a wire rope, two detection probes are placed on the outside of the wire rope. The wire rope is tested through the detection probes. The detection mechanism is installed on the rocker arm. The detection mechanism can swing up and down and left and right with the rocker arm. At the same time, the detection mechanism can adjust the angle on the rocker arm.

[0029] 2. A tension spring is connected between the connecting rod and the rocker arm to provide tension to balance the gravity of the rocker arm and its upper part to generate torque, so as to maintain the stability of the rocker arm during movement;

[0042] The following is combined with Figure 1-5 The present invention is described in further detail.

[0043] The embodiment of the present invention discloses a swinging steel wire rope detection device.

[0044] Reference Figure 1 The swinging wire rope detection device includes a fixed base 1, a detection mechanism 2 and a swinging mechanism 3; the detection mechanism 2 is installed on the fixed base 1 through the swinging mechanism 3. When the winch reels the wire rope, the wire rope is detected by the detection mechanism 2. The swinging mechanism 3 enables the detection mechanism 2 to move synchronously with the swing of the wire rope, so as to be suitable for detecting the swinging wire rope.

[0045] In order to improve the stability of the fixed base 1, one end of the fixed base 1 is fixedly connected to a connecting part 11 for connecting the winch. When the fixed base 1 is installed, the connecting part 11 is fixedly connected to the winch as a whole by bolts 2112. A support assembly 12 is also provided between the fixed base 1 and the winch. Specifically, the support assembly 12 includes a connecting plate 121 and a support rod 122. One end of the support rod 122 is welded to the connecting plate 121, and the other end of the support rod 122 is welded to the fixed base 1. A triangular structure is formed between the support rod 122, the fixed base 1 and the winch, thereby improving the stability between the fixed base 1 and the winch.

[0046] In this embodiment, the swing mechanism 3 includes a rocker arm 31, a first movable connection component 32 and a second movable connection component 33; one end of the rocker arm 31 is connected to the fixed base 1 through the first movable connection component 32, and the detection mechanism 2 is installed on the other end of the rocker arm 31 through the second movable connection component 33. The detection mechanism 2 is realized by the rocker arm 31 and the first movable connection component 32 to swing left and right and up and down; the detection mechanism 2 is realized by the second movable connection component 33 to swing left and right and up and down.

[0047] In order to realize the detection of the wire rope, the detection mechanism 2 includes a positioning component 21 and two semicircular detection probes 22. The detection probe 22 of the present application is a leakage magnetic detection probe, which is used to perform non-destructive detection on the wire rope. A detection area is formed between the two detection probes 22. The positioning component 21 is used to fix the positions of the two detection probes 22. During detection, the two detection probes 22 are sleeved on the outside of the wire rope, and the positioning component 21 is used to make the wire rope located in the middle of the two detection probes 22.

[0048] The positioning assembly 21 includes two horizontally placed brackets 211. The bracket 211 located at the bottom is connected to the rocker arm 31. One side of the two brackets 211 can be opened and closed by a hinge 2111, thereby realizing the opening and closing of the two brackets 211. One side of the two detection probes 22 can be opened and closed by a hinge 221, and the opening and closing direction is the same as the opening and closing direction of the two brackets 211. One of the detection probes 22 is fixedly connected to the bracket 211 on the same side, and the wire rope is passed through the two detection probes 22. The other side of the two detection probes 22 is detachably connected, and any one of bolt connection, buckle connection, and spring elastic connection is adopted to form a closed space for the two detection probes 22. The other side of the two brackets 211 is connected by bolts 2112, so that the two brackets 211 are connected and fixed, and the two brackets 211 are also sleeved on the outside of the wire rope.

[0049] In this embodiment, the positioning assembly 21 also includes a roller frame 212, a roller 213 and an adjusting member 214. The roller 213 is rotatably connected to the roller frame 212, and the roller frame 212 is rotatably connected to the inner wall of the bracket 211. The rotation axes of the roller frame 212 and the roller 213 are parallel to each other and perpendicular to the wire rope. Both ends of each bracket 211 are rotatably connected to the roller frame 212 that drives the roller 213, so that when the wire rope passes through the bracket 211 and the detection probe 22, the rollers 213 on the two brackets 211 abut against the outer wall of the wire rope to be tested. The adjusting member 214 is used to drive the roller frame 212 to rotate so that the roller 213 abuts against the outer wall of the wire rope during detection. The rotation stiffness of the roller frame 212 is adjusted by the adjusting member 214 to adjust the abutting force and keep the wire rope located in the middle of the two detection probes 22.

[0050] As a preferred embodiment, the adjusting member 214 includes an articulated screw 2141, a spring 2142, a first support seat 2143, a second support seat 2144 and a nut 2145. One end of the articulated screw 2141 is rotatably connected to the end of the roller frame 212 away from the roller 213. The first support seat 2143 is fixedly connected to the bracket 211. The articulated screw 2141 passes through the first support seat 2143, the spring 2142, the second support seat 2144 and the nut 2145 in sequence. The articulated screw 2141 is threadedly connected to the nut 2145. When the wire rope is relatively clean, the rotational stiffness of the roller frame 212 is increased, so that the detection probe 22 follows the wire rope closely, ensuring that the relative displacement in the cross section remains unchanged, and obtaining better quality. To collect signals, rotate the nut 2145 to adjust its position on the articulated screw 2141, drive the second support seat 2144 to compress the spring 2142, and when the spring 2142 drives the second support seat 2144 and the articulated screw 2141 to move in opposite directions, the roller frame 212 rotates, thereby increasing the force between the roller 213 and the wire rope, further improving the stability between the bracket 211 and the wire rope; when there is a lot of oil, dust, stones, etc. on the wire rope, a relatively small rotational stiffness is required for the roller frame 212. If a larger rotational stiffness is used, the impurities on the wire rope will cause the probe to move violently, resulting in unstable signals. In addition, the collision of impurities with the roller 213 will cause the wire rope to be scratched, so the nut 2145 is rotated in the opposite direction for adjustment.

[0051] In order to install the bracket 211 on the rocker arm 31, the second movable connection assembly 33 includes a second rotating seat 331 and a second connecting frame. The second connecting frame is rotatably connected to the rocker arm 31 and the rotating axis is horizontally arranged. The second rotating seat 331 is fixedly connected to the second connecting frame. The bracket 211 located below is fixedly connected to the second rotating seat 331, and the rotating axis of the bracket 211 is perpendicular to the rotating axis of the second connecting frame. By rotating the second connecting frame, the detection probe 22 can be swung up and down. By rotating the second rotating seat 331, the detection probe 22 can be rotated in the horizontal direction. When the wire rope swings, the bracket 211 and the detection probe 22 are first adjusted in angle as the angle of the wire rope changes.

[0052] In this embodiment, the first movable connection component 32 includes a first rotating seat 321, a first connecting frame 322, a connecting rod 323 and a plurality of tension springs 324. The first rotating seat 321 is rotatably connected to the fixed base 1 and the rotating axis is vertically arranged. The first connecting frame 322 is fixedly connected to the outer peripheral wall of the first rotating seat 321. The rocker arm 31 is rotatably connected to the first connecting frame 322 and the rotating axis is parallel to the rotating axis between the rocker arm 31 and the second connecting frame. The connecting rod 323 is fixedly connected to the first rotating seat 321. A plurality of tension springs 324 are arranged parallel to each other and connected to the connecting rod 323. A tension spring 324 is used between the rod 323 and the rocker arm 31 to provide tension for the rocker arm 31 to balance the gravity of the rocker arm 31 and its upper part to generate torque, thereby maintaining the stability of the rocker arm 31 during movement. An extension rod 325 is fixedly connected to the connecting rod 323 and the rocker arm 31. The extension rod 325 is parallel to the rotation axis of the rocker arm 31. A plurality of positioning grooves 3251 are provided on the extension rod 325. Both ends of the tension spring 324 are fixedly connected to a connecting ring 3241 which is sleeved on the extension rod 325 and embedded in the positioning groove 3251, thereby improving the stability of the installation of the tension spring 324.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
